Nail fungus among other dis-eases in the human body is caused by the crap we intake into our bodies that we think is food and actually is not. Garbage in garbage out. Age does play a roll in this as the older we are the more time we've had to ingest more crap building layers of it in our bodies to turn them acidic therefore shutting down the kidneys and backing up our lymphatic system(sewer system of the body) hence, just as a clogged toilet backing up in the body. All issues from STD's to cancer to nail fungus wouldn't be an issue if we provided our bodies with "only what they required and not all the crap we want or think is actual food. Not to mention fluoride and chlorine in the water, vaccines, chem-trails, big pharma and the list could go on for eons. The kidneys would function. The lymph would move as it's supposed to and we would be pictures of good health. Is it possible to live this way in our world today? Baby steps my friends, baby steps. Small changes here and there add up big time for health just as saving pennies turns to $'s. It's your health and your most important asset. Take care of it. Enjoyed E.
